Eucalyptus logs are obtained from cutting eucalyptus trees, which requires level 58 Woodcutting. They cannot be fletched and give 193.5 Firemaking experience when burned. The only location eucalyptus trees can be found is west of Oo'glog. They were first introduced on 29 January2008 with the As a First Resort...quest, and a minimum of 15 eucalyptus logs are needed to complete the quest. Being close to a bank and extremely lightweight, this makes chopping eucalyptus trees a very efficient way to make money. There is also is a spirit tree nearby which can be used to get to the Grand Exchange quickly. However, this area may be dangerous for lower levels as many wolves live in the area and are aggressive to lower levels. There are a few safe spots where they cannot attack players, namely northeast near the hunting grounds. The safest place to cut Eucalyptus logs is directly next to the Og'glog lodestone where there are no wolves. Eucalyptus logs can be more efficient when making money than yews, since most yews near banks have many people chopping them.

Eucalyptus logs are commonly used as either pyre logs or just for making fires and give almost the same amount of Firemaking experience as yew logs.

One method of training multiple skills at once is to bring along a hatchet, a tinderbox and a bird snare or two. Players can cut eucalyptus trees and burn their logs while waiting for the traps to catch tropical wagtails (Hunter level 19 required, level 20 required for 2 traps at once). They can also cook the raw bird meat for Cooking experience and food to heal the occasional hits by the Wolves. Players can then train Woodcutting, Firemaking, and Cooking and Hunter all at once, making this an ideal training area for players with lower levels in those skills.

Eucalyptus logs were a very popular log of choice for Firemaking training after the release of the tool belt, as they could be lit with one click after a tinderbox was added to the belt; however, this changed after the introduction of bonfires and the new craft-X interface.

Eucalyptus logs cannot be used in the Fletching skill. If a player tries to fletch a eucalyptus log, the following message is displayed: "These stringy-barked logs aren't good for making bows or arrow shafts".
